# Flask2Neo4J
Extension Flask for integration with neo4j graph database
## Installation
Using pip:
```
$ pip install flask2neo4j
```
## Usage
Basic Step to usage this extension:
1. Create Flask app instance:
```
import bcrypt
from py2neo import ogm
from flask import Flask, request
from flask2neo4j import Flask2Neo4J
app = Flask(__name__)
```
2. Add NEO4J Config and Initialization Flask2Neo4j Extensions:
```
app.config["NEO4J_USERNAME"] = "neo4j"
app.config["NEO4J_PASSWORD"] = "neo4j"
app.config["NEO4J_URI"] = "bolt://localhost:7687"
flask2neo = Flask2Neo4J()
flask2neo.init_app(app)
```
3. Create Model using Graph Object if using GraphObject
```
class Users(ogm.GraphObject):
__primarykey__ = "id"
id = ogm.Property()
username = ogm.Property("username")
password = ogm.Property("password")
def create_password(self, password):
self.password = str(bcrypt.encrypt(password))
@property
def is_exist(self):
return flask2neo.graph.exists(self)
def save(self):
if self.is_exist:
flask2neo.graph.merge(self)
flask2neo.graph.push(self)
else:
flask2neo.graph.create(self)
```
4. Define function register as flask request method ```POST```
```
@app.route("/register", methods=["POST"])
def register():
form = request.form
user = Users()
user.username = form['username']
user.create_password(form['password'])
user.save()
return "User Created"
```
5. Run flask app
```
if __name__ == '__main__':
app.run(port=8500, debug=True)
```
Open your browser and type into url : ```http://localhost:8500```
